Review official results
One lesson to investigate in future events.
- Read the original forecast before the outcome.
- Check the recorded official result and source context.
- Record a lesson without treating one result as proof.
20 reported evidence limits. Agreement alone does not establish accuracy.
A probability difference alone does not account for forecast error, fees, spread, or available liquidity.
Why the models lean this way
These are reasons recorded by the models. They are not independently verified facts or measured causes of a probability change.
- Grok: Jodar current rank 12
- Claude: Jodar ranked No. 12 vs Ruud No. 20 — modest ranking edge to Jodar
- GPT: Rafael Jodar has the better current ranking (12 vs 20).
- Gemini: Rafael Jodar is ranked No. 12.

Grok · Rafael Jodar · 57.0%
Jodar holds the superior current rank (12 versus Ruud's 20). This is the sole quantitative fact supplied. Surface form, injuries, head-to-head, travel, and market odds are unavailable and therefore excluded from the estimate. The modest rank gap supports only a slight edge for the higher-ranked player.
xai/grok-4.3 · Oct 15, 11:01 PM PDTClaude · Rafael Jodar · 56.0%
The evidence package supplies only current ATP ranks: Rafael Jodar at No. 12 and Casper Ruud at No. 20. An eight-place gap near the top-20 band is a modest edge, historically translating to roughly a 54-58% win probability for the higher-ranked player in a best-of-three ATP Masters quarterfinal. No season win-loss records, ranking points, titles, surface-specific form, injury status, head-to-head history, travel/fatigue information, or market odds are provided, so no adjustment away from the rank-implied baseline is justified. I therefore set a modest lean toward Jodar with low confidence.
anthropic/claude-opus-5 · Oct 15, 11:01 PM PDTGPT · Rafael Jodar · 56.0%
Using only the supplied immutable evidence, the main differentiator is current ranking: Rafael Jodar is ranked No. 12 and Casper Ruud is ranked No. 20. No season win-loss records are actually provided in the evidence payload, so the estimate must rely primarily on ranking. That gives Jodar a modest edge, but not a large one, because rankings alone are an incomplete basis for a single-match forecast between two high-level ATP players in a quarterfinal. Surface form, injuries, head-to-head, travel, and market odds are unavailable, and those missing factors materially limit certainty.
openai/gpt-5.4 · Oct 15, 11:01 PM PDTGemini · Rafael Jodar · 56.0%
Rafael Jodar holds a higher ATP ranking at No. 12 compared to Casper Ruud at No. 20. With no season win-loss records or other contextual data available, the higher-ranked player is given a slight edge in this matchup.
